| 摘要: |
| 总结了兴安直流输电系统2012年度的运行情况，统计了能量可用率、强迫能量不可用率、传输电量等主要运行指标。分析了直流闭锁、直流紧急停运、直流临时停运等影响直流可靠性的基础事件。对兴安直流2012年度直流保护不正确动作事件和典型事件进行分析，详细介绍了事件原因、暴露问题、现场处理、反措落实等。针对事件暴露出的问题集中在二次回路上，且在过去的检修维护工作中，有“重装置、轻回路”的思想，提出今后的检修工作中要有“重回路、轻逻辑”的思路，并重视备用回路的检查。这些经验不但为直流输电系统的运行、检修提供有益的参考，还有助于提高直流输电系统的运行维护水平，确保系统的稳定运行。 |

| Abstract: |
| The operation condition of Xing-An HVDC Project in 2012 is analyzed, the operation indexes such as energy availability, forced energy unavailability, transmission power are summarized. The events which affect the reliability of HVDC project such as DC blocking, ESOF, DC temporary outage are analyzed. The protection maloperation events and typical events are analyzed, whose causes, problems exposed, on-site treatments and counter-measurements are introduced in detail. Contrary to that the problems the events exposed focus on the secondary circuits, and in the repair and maintenance work in the past, there is idea "heavy equipment, light circuit", a new idea "heavy circuit, light logic" is put forward in the future maintenance work, and emphasizing the standby loop circuit checks. All above are not only valuable to improve the ability of operation and maintenance to ensure the safety and the reliability of HVDC system, but also benefit to improve the design, commissioning and operation level of HVDC power transmission projects in China in the future． |
